Venous pressure during intravenous regional anesthesia: Implications for setting tourniquet pressure

Evaluation of the Tourniquet Leak during Forearm Intravenous Regional Anesthesia

Methods: A crossover randomized study of IVRA with a forearm tourniquet was conducted on 14 male healthy volunteers. This study was performed, once using manual injection of local anesthetic and once using automatic pump injection, on two separate sessions. In both techniques, 0.3 ml/kg lidocaine 0.5% was injected over 90 seconds. The occlusion pressure, continuous venous pressure and the serum...

Simple Arm Tourniquet as an Adjunct to Double-Cuff Tourniquet in Intravenous Regional Anesthesia

BACKGROUND Intravenous Regional Anesthesia (IVRA) is a well-known technique for producing analgesia during surgical procedures in the extremities. However, the rapid onset of pain following the deflation of a double-cuff tourniquet during IVRA is a serious disadvantage, leading patient suffering. OBJECTIVES The aim of this study was to evaluate the clinical effectiveness of a pneumatic arm to...

Determination of Central Venous Pressure from Intraocular Pressure

Background: In many clinical situations, knowledge of central venous pressure (CVP) is important.  Measurement of CVP is not always possible. Objective: To determine if intraocular pressure (IOP) can be used as an estimate for CVP. Methods: IOP and CVP were measured concurrently in 30 candidates of coronary artery bypass graft surgery.  Those with carotid artery or jugular venous diseases as we...

simple arm tourniquet as an adjunct to double-cuff tourniquet in intravenous regional anesthesia

conclusions this study showed that a pneumatic arm tourniquet as an adjunct to ivra provides acceptable analgesia following the deflation of the double- cuff tourniquet for relieving surgical pain. results the mean operation time after the deflation of the double-cuff tourniquet was 20.12 ± 6.1 minutes. moreover, the mean nrs for the post-deflation time was insignificant (nrs = 2), and only one...
